Abstract:
In this proposal, we will define the injection momentum of the MI as 8.851 GeV and the injection frequency will be 52809500 Hz. The extraction energy of the Booster will be reduced by 38 MeV. In this scheme, a “mini-ramp” matched to the current Accumulator energy will be used for reverse proton tuning and pbar transfers to the Recycler, until the Debuncher frequency jump can be implemented. The energy of the pbar source will NOT change. Once the Debuncher frequency jump is implemented, the 8 GeV mini-ramp will be removed and the cycle will become 8 GeV DC.
